Callisto and Io Picture

Ok~ So, if you guys know Callisto and Io, not the mythology versions, the moons xD then you know that these two are two of the many many moons of Jupiter. Io is personally a fave, I don't know why, but it is lol

And, I know in the mythology, Callisto and Io are nymphs, but I don't care lol Callisto and Io are for me and my gf's planet family xD

Callisto is the one in the blue (the one on the bottom ;D)Io is the one in purple (the one on top ;D)
